HOW TO: convert a System.Runtime.InteropServices.FILETIME into a System.DateTime and back again
Added On: 12/14/2003 Blurb Eventually, everyone works with an unmanaged Win32 API in .NET that returns you information in the form of a FILETIME struct. But, a .NET programmer is used to working with a DateTime struct. This code converts FILETIME to DateTime and DateTime to FILETIME... just everything a growing programmer needs. Sample C# Code
using System;
using System.Runtime.InteropServices;
namespace ClassLibrary3
{
class __Loader
{
// HOWTO: convert a System.Runtime.InteropServices.FILETIME
// into a System.DateTime and back again
static void Main()
{
FILETIME ft = new FILETIME();
/
//from System.DateTime to System.Runtime.InteropServices.FILETIME
/
long hFT1 = DateTime.Now.ToFileTimeUtc();
ft.dwLowDateTime = (int) (hFT1 & 0xFFFFFFFF);
ft.dwHighDateTime = (int) (hFT1 >> 32);
/
//from System.Runtime.InteropServices.FILETIME to System.DateTime
/
long hFT2 = (((long) ft.dwHighDateTime) << 32) + ft.dwLowDateTime;
DateTime dte = DateTime.FromFileTimeUtc(hFT2);
Console.WriteLine(dte);
}
}
}
